Installation Instructions
1.
Remove your antenna from package and verify its contents to insure it is complete.
2.
For a maximum strength and performance of your
PWR-4CROSS
, it´s very important to choose a proper
mounting location, with a good vehicle ground.
Matching network is compensated for trunk lid mounting and not recommended for centre roof mounting nor
magnet base.
3.
Install your
PWR-4CROSS
antenna on vehicle. Be sure that your trunk-lid makes good contact and it´s properly
fixed for your personal security.
4.
Use a quality VSWR meter and check V.S.W.R. of each band for a proper tuning.
A
djustment
Firstly, check VSWR on 6 meters:
Loosen set-screws (
PWR01006
) on base coil (
PWR01007
) and
then find the centre of frequency for a best performance of
your
PWR-4CROSS
.
Upon obtains an acceptable VSWR on 6 meters & 2 meters,
tighten set-screws (
PWR01006
) strong.
Please follow the same instructions to adjust properly the 10
meters band by the tuning whip: Raising the whip
(
PWR01001
) will affect both, 6 meters & 10 meters centre
frequency.
It is best to tune the 6 meters band first to reach optimum
centre frequency, then proceed to adjust for 10 meters
optimum centre frequency.
Tune until obtain a satisfactory VSWR at both 6 meters & 10
meters centre frequency.
Verify setting results in best fit for each band.
Tighten set screw (
PWR01008
) using removable “Loctite” or
similar product to insure a proper fastening of setscrews and
whip section.
In case you have difficulty in tuning the 10 meters & 6 meters
bands, the cause would be most likely attributed to grounding
characteristics of the vehicle trunk lid.
It is sometimes necessary to add short grounding straps or
copper braid from trunk lid to body panel, to lower resonant
frequency.
